Vāta — pakvāśaya / colon
Principal Vāta seat
Pakvāśaya, conventionally translated as the colon or large-intestinal region, is the principal Vāta seat and the governing anchor of this system. The large radius highlights its doctrinal priority; the front-view position is a schematic projection of a deep abdominal organ, not a claim about a single palpable surface point.
